Application Ytiled March 15,

To all @07mm t may concern.'

Be it known that I, JOSEPH REN AYOTTE, a subject of the King of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hand-Tools, of which the following is a specification.

This invention relates to certain improvements in hand tools, such as wrenches and the like, it being an object to so construct the implement that it may be easily operated and applied to parts that are-located in relatively inaccessible places; that it have a longitudinally eXtensible handle adapted to operate conveniently under different conditions; that it have means for holding a tooll socket which is formed specially to cooperate with the parts to beacted upon; and that its component parts be so Varranged and'comined as to produce a strong, durable, and

f eilicient construction.

This invention further resides in numerous other features of construction and combinations of parts all of which will more clearly hereinafter appear in the yspecification to follow, wherein reference is made to the accompanying drawing which exhibits an exemplification of this invention in the lmanner following Figure 1 shows in sideelevation the` tool' with its operatinghandle in extended position, the tool socket beingV shown as detached from the implement;

Fig. 2 is a longitudinal section' through the implement, the operating handle` being in telescoped position; K

Fig. 3 is a detail, principally in elevation,

a portion vof the view, however, representing a section taken online 3-3 of Fig. 2; and

Figs; 1, 5, and 6 are enlarged transverse sections taken, respectively, on lines '1l-11, 5 5, and 6-6 of Fig. 2:

In the embodiment of the invention illustrated on the accompanying drawing, the toolcomprises a bodyjin the form of an outer casing A which surrounds a sleeve B within which is an extensible tube C. At its lower'.l end the sleeve is connected asby means of a universal joint 10 with a holderl D' havingla head lporti'onll lin overlying' relation to the proximate' end of the casingv A, which is preferably bent at an angle relative to the main portion of the tool. Any suitable opening 12 may' be formed in the casing bend near the joint l0, as shown, to facili- Specication of Letters Patent.

tate the assembly and lubrication of the partsinside. At its other end the sleeve BV is formed with a head 13 which overlies the upper end of the casing. By means of the holder head at one end and the sleeve head at the other end, the sleeve and holder are maintained as a unit in a position within the casing.

Through the medium of the sleeve rotary motion may be communicated vto the holder D which is formed to receive al tool or socket memberrE (see Fig. 1) that is adapted to engage with the work. For this purpose, the holder is preferably formed interiorly with 1 polygonal faces 15 beyond which are onevor more annular recesses 16 within each of which is located a spring ring 17. The toolV or socket member which cooperates with the holder thus formed is also provided with corresponding vpolygonal faces 18 so as to lit non-rotatably within the holder, and is further provided with a head on which are formed a plurality of annular grooves 19 each of which may receive one of the spring' rings 17 when forced into registering positivonrelative thereto. According to this construction, the socket member may be slipped in and out of thev holder against the cornbincd tension of the split'rings whosenormal tendency is to-hold the socket member operatively in position. By employing a plurality of rings and grooves as shown, I provide a more secure fastening for thetool member than would otherwise be possible.

In the operation of the tool, its body is held against rotation while the sleeve B is rotated. This is accomplished through the medium of the tube C which is nonrotatably connected to the sleeve B as by means yof a key 20 that is received within a slot V21 formed inthe head 12B-of the sleeve B. This slotL extends downwardly from the upper end of the head close yto its shoulder 22 'which abuts the/upper end of the casing 'When'the key is slipped in place within theuslot, itis confined as-by means of a'ca'p 25 which'is threaded to" screw onto the upper end of the Sleeve head 13 as best shown in Fig. 2r. Interiorly the cap is `formed with a shoulder 26 which overlies the sleeve head as well as the slot 21 therein. Adjacent the shoulder 26 is anv annular groove 27 within which is seated a spring ring 28 that is adapted to engage within any one of several annular grooves 29 that are formed eX- fiXed longitudinal teriorly of the tube C. As illustrated in Fig. 2, this spring 28 is seated within the uppermost groove 29 so as to normally maintain the handle in telescoped position as shown. lli/Then, however, the handle is extended as shown in Fig'. 1, the spring` ring 28 will seat within another groove 29 so as tain the handle in a definite position of adjustment. Other adjustments, of course, are permissible, depending upon the number and location of the grooves 29 within any one of which the ring 28 coperates by friction to maintain the parts in certain relative positions. The tube C is provided also Vwith a longitudinal groove 30 into which the key 2O projects so as to prevent relative rotary movement vbetween the tube and sleeve B, regardless of the distance to which the tube may have been extended longitudinally thereof. This groove may be conveniently formed by constructing the tube of two parts-an inner sleeve 31 around which is wrapped a plate 32 having its meeting edges slightly spaced apart to form the groove B0. rlhis plate 32 may be ccnveniently welded to the sleeve 31 so that the tube C, to all intents and purposes, represents an integral construction.

The construction thus far described provides for a driving connection between the tube C and/the socket member E regardless of the longitudinal adjustment of the tube relative to the casing. Other means for imparting rotation to the tube are also provided which preferably consist of a stud 35 non-rotatably locked to the tube C as by means of a cross pin 36, this stud extending exteriorly beyond the cap 25 and having a head 37 by which is secured to the cap and tube C a hub 38. Within the hub is formed a recess 40 that encircles the stud and which receives a toothed wheel 41 that is locked to the stud as by means of a cross pin 42. Within this same recess 40 are mounted a pair of dogs 43 eac pivoted as at 44t0 swing into or out of engaging position relative to the teeth of the wheel 40 for the purpose of actuating the same in either or both directions. These dogs are held in either operative or inoperative position as by means of a spring 45 which is secured in place by a pin 46, the spring having two arms one of which is in operative relation with each dog. The operative relation of the dogs to the wheel is of the usual kind to provide a ratchet working one or both ways, depending upon which dog is engaged with i the wheel.

Extending laterally from the hub 38 is an arm 48 that-is socketed to receivev the end of an operating lever 50 which may be of any convenient size and shape. Asshown in the drawing, the endk of the lever which lits within the arm socket is grooved as at 51, a second groove 52 being formed in the to main-y arm to retain'therewithin a spring ring 53 which cooperates with the groove 51 to maintain the lever in place. It may be desirable that the crank have its free end 54 laterally turned to facilitate use of the tool, and the construction that l have shown between the crank and arm is such as to permit the lever to turn about its own axis while still maintaining connection with the handle.

I would have it understood, however, thatl in lieu of a single groove 52 and spring retained therein, two or more such grooves or springs might be used to supplement the locking connection. Also, if preferred, another form of connection might be used, such, for instance, as an ordinary screwthread, to maintain the lever in operative relation to the handle.

The implement that l havefdescribed is exceedingly simple in its construction, and in the operationswhich are requisite to its use. The character of lock which maintains the handle in any given longitudinal position of adjustment relative to the body is sufiicient force to overcome the tension of the split spring ring that is used, and, if preferred, this tension may be augmented by the use of two or more springs should this be found desirable. lt is manifest, of course, that the tool may be constructed to any desired proportions and of any suitable materials. Changes or modifications may obviously be made without sacrificing the 100 features of advantage herein described, and in so far as such constructions answer to the claims of this invention as dened below, I desire that they be included within the scope of this patent.
